PURPOSE: A three dimensional recursive moving vector estimated apparatus is provided to improve an accuracy of a moving vector estimated by searching an initial moving vector and then outputting block video information of prior frame corresponding to a present block, or estimating a final moving vector including a moving degree of the present block and surrounding the block. CONSTITUTION: A moving vector storing unit(10) stores a moving vector of a block computed between moving vector about each block of a prior frame and a block of a present frame. And then, the moving vector storing unit(10) outputs the moving vector of a surrounding block neighboring the present block according to location information of the present block. An initial vector computing unit(20) receives the moving vector of the surrounding block outputted from the moving vector storing unit(10), and then outputs the initial moving vector for the present block. A moving compensation unit(30) compensates the inputted prior frame video information according to the initial moving vector, and outputs block video information of the prior frame corresponding to the present block. A frame difference signal compensation unit(40) calculates the difference between the video information of the present block and the block video information of the prior moving vector compensated, and outputs a frame difference signal. A horizontal/vertical difference signal compensation unit(60) inputs the video information of the present block, and outputs a horizontal difference signal between pixels in the present block. A moving vector compensation unit(50) inputs the frame difference signal, horizontal difference signal and the vertical difference signal, and compensates the moving vector for the present block, and then adds the result to the initial moving vector from the initial vector computing unit(20) to output a final moving vector and feedback the outputted final moving vector to the moving vector storing unit(10). |
